Electric shocks can cause death or severe injury. Proceed with extreme care when touching cables and terminals. If the device/measuring system is installed in a high-voltage environment and malfunctions or installation errors occur, the terminals or the device/measuring system themselves might be high-voltage energized. 1.1 Designated use Smartec S CLD134 is a field-tested and reliable transmitter used to determine the conductivity of liquid media. It is particularly suitable for use in the foodstuffs industry. Any other use than the one described here compromises the safety of persons and the entire measuring system and is, therefore, not permitted. The manufacturer is not liable for damage caused by improper or non-designated use. 1.2 Installation, commissioning and operation The device/measuring system may only be installed, connected, operated and maintained by trained technical personnel (e.g. certified electrician). The technical personnel must strictly adhere to the Operating Instructions, prevailing standards, legal regulations and certificates (depending on application). If the Brief Operating Instructions do not provide sufficient information, you must read the Operating Instructions. There, you can find detailed information on the device. The operator may only perform modifications and repairs of the device/measuring system that are explicitly permitted in the Operating Instructions. Do not operate damaged products and secure them against unintentional commissioning. Mark the damaged product as being defective. If faults can not be rectified, the products must be taken out of service and secured against unintentional commissioning. 2 Endress+Hauser

4 Wiring Smartec S CLD Installation of the compact version or CLS54 sensor for separate version! Note! Perform an air set and calibrate the sensor before installing the compact version or the sensor. Install the compact version or the CLS54 sensor directly on the pipe or vessel socket via the process connection (depending on ordered version). 1. When installing the Smartec S CLD134 or the sensor, make sure that the flow opening of the sensor is oriented in the flow direction of the medium. An orientation arrow on the sensor facilitates orientation. 2. Tighten the flange. 3 Wiring # Warning! The electrical connection must only be carried out by a certified electrician. Technical personnel must have read and understood the instructions in this manual and must adhere to them. Ensure that there is no voltage at the power cable before beginning the connection work. 3.1 Cable glands A B Fig. 2: Terminal assignment of cable glands A Separate version 1 Cable gland for analog output, binary input 2 Cable gland for alarm contact 3 Cable gland for power supply 4 Housing ground 5 Pressure comp. element PCE (Goretex - filter) 6 Cable gland for sensor connection, M 16x1.5 B Compact version Cable gland for analog output, binary input Cable gland for alarm contact Cable gland for power supply Housing ground Pressure comp. element PCE (Goretex - filter) a Endress+Hauser
